Vietnam Airlines close call at Munich yesterday

[drron]

Their 787 went past the runway before becoming airborne yesterday. Got to 9000 feet. dumped fuel and returned to Munich. Several tyres blew on landing and stuck for while disrupting traffic

.

Another for the no fly list.

And tail strike trying to get it off the ground

Passenger perspective

Not clear if tail or fence strike

Seems possibly similar to EK407 at MEL in 2009.

Two interesting short videos regarding this incident.

From inside the cabin. Flaps are down and I have no idea if they are the correct level. The takeoff roll seems to be very 'laboured' to my untutored eye. The video also shows that they were on the grass for quite a way.

Edit: I have removed this video as it seems to be on autoplay. If you are interested it should be easy to find it.

The second video is from the ground on the runway and shows what appear to be skid marks at the very end of the runway heading into the grass.

These spotters captured the fly pasts and the landing (1:38, it is a very long video) where the tyres shredding clearly visible.

Found the ‘in cabin’ video… yikes! That’s painful to watch

The plane seems to reach a certain speed and then… nothing… just keeps going at the same speed. Until it runs out of runway.

There are images showing both a large hole ripped in the tail and also multiple holes in the vertical stabiliser.

What a bizarre series of events.

I don't see how the pilots come out of this looking good. The runway at MUC is very long. I heard one rumour in German aviation circles that the brakes were partially applied during the take-off roll.

I wonder when was it that reduced power take-offs became normal ops.

Those 'skid marks' in the video I posted above look a bit that way.

On FR24, reasonably coarse data suggests the problem flight had an (eventual) take-off speed of 185 knots

https://www.flightradar24.com/data/flights/vn34#412f683a

A few days earlier, same position on the runway,202 knots.

https://www.flightradar24.com/data/flights/vn34#411a19ad

But a few days prior to that, 192 knots.

No idea if any of that is significant.

Can't see tail strike scrape marks on the fly pasts

I wonder when was it that reduced power take-offs became normal ops.

Flex or "derated" thrusts became very common with "digital" FADEC - full authority digital engine control or similar depending on engine manufacturer

Prior to that the I think the flight engineers would have had to manually calculate it using engine performance charts.

It was to prolong engine life and reduce maintenance because full thrust takeoffs was associated with extreme internal temperatures. So it was used when departing with less payload, longer runways and favourable takeoff conditions.

I think the 747-400 had them but not the classics.

The opposite of derate thrust would be thrust augmentation using water injection which reduced internal temperatures and increased mass airflow allowing more fuel . Not used these days.

Theres photos floating around.
